ICE-CREAM FRE EZER.

SPECIFICATION forming part of Letters Patent No. 664,214., dated May 17,1898.

Application filed March 2, 1897.

To all whom it may concern:

Be it known that we, ROBERT L. PORTER and JOSEPH D. FAULKNER, citizensof the United States of America, residing at Galena, in the county ofCherokee and State of Kansas, have invented certain new and usefulImprovements in Ice-Cream Freezers, of which the following is aspecification, reference bein g had therein to the accompanyingdrawings.

Our invention relates to improvements in ice-cream freezers; and it hasfor its object to simplify, improve, andcheapen the cost of constructionof this class of freezers over the existing prior state of the art.

With these ends in view the invention consists in the novel constructionand arrangements of the several parts, as will be hereinafter more fullydescribed, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is a top plan View, partly brokenaway. Fig. 2 is a vertical sectional View. Fig. 3 is a detail view ofone of the cream-holding tubes.

Similar letters of reference indicate corresponding parts in the severalviews.

Referring by letter to the accompanying drawings, A designates arectangular box provided with three compartments, the centralcompartment a being somewhat larger than the two outside or adjacentcompartments a These compartments are formed by perpendicular metallicpartitions a and a The box is provided with vertical central slots 13 Bat'each end, these slots serving as bearings for the reception ofjournals in the ends of a rotating cylinder, which will be herein aftermore fully explained.

G O are ways or guides secured upon the outside and centrally at eachend of the box or casing A and adjacent to the slots B-B, these ways orguides receiving adjusting slides or keepers c c for holding thejournals of the cylinder, heretofore mentioned, in its proper place.

The compartment of the box or outside casing A is further provided withthe usual hinged covers D D D in ordinary use.

E E E designate pivoted latches, one, or

- E, being pivoted to the box in front of the larger compartment, andthe others, E and E at each end thereof adjacent to the smallercompartments, as clearly shown in the drawings.

in the vertical bearing-slots B B, one of said journals 9 terminating inan operating-crank H, by means of which the cylinder is revolved. Thiscylinderis provided with one or more longitudinal angular strips I, theends of which are secured to the ends of the cylinder, the apex of thestrips resting upon the inner wall of the circumference of the cylinder.These strips I serve as seats for a number of creamholding tubes, thenumber used being more orless, according to the size of the cylinder inuse.

J designates acream-holding tube, the ends of which are left open in itsconstruction, and around the outer surface of these ends are cutscrew-threads, which are adapted to receive a cap. These caps are alsoscrew-threaded correspondingly and fit tight and snugly upon the ends ofthe tubes,suitable packing of cork, rubber, or other similar materialbeing interposed between the caps and the ends of the tubes within thecaps,which act to prevent any liability of leakage. These tubes aregrouped or arranged longitudinally with respect to each other around theinner wall of the cylinder sufficiently snug as to prevent accidentaldisplacement.

K designates a hinged curvilinear cover which is hinged to the cylinder,as shown in the drawings, the curve therein corresponding to the curvein the cylinder, so that when the cover is closed over the opening inthe cylinder the meeting edges of the cover and cylinder will lie flushwith each other. The portion of the cylinder opposite the longitudinalopening is perforated sufficiently to allow the passage of waste waterand other foreign matter from the cylinder.

L designates a latch curved to conform to the curve in the cover of thecylinder and pivoted at its near end centrally in a longitudinaldirection to the rear portion, the forward end of the latch having acurved notch therein which passes a pin secured in the cylinder in frontof the cover, this latch serving to properly fasten down the cover whenthe cylinder is in use.

The smaller compartments a and a serve as refrigerators for holdin andkeeping cool soft drinks, such as pop, soda, &c.

From the foregoing description, taken in connection with theaccompanying drawings, the operation of our device will be obvious; butit may be briefly rehearsed as follows: Preparatory to freezing thecream the tubes are filled by removing one of the screw-caps of eachtube, after which replace the caps.

and arrange the tubes in the freezing-cylinder as hereinbeforedescribed, packing the same with ice and salt. Then close down the lidor cover of the cylinder and also the cover of the box or outsidecasing, when the freezin g-cylinder is then revolved by means of thecrank.

When it becomes necessary to remove the cream from the several tubes,remove both caps of the tubes and then use a round rod, pressing throughthe tubes, which forces the cream out.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

In an ice-cream freezer, the combination of a casing having compartmentstherein, With a rotary freezing-cylinder supported in bearings in theends. of the casing, adapted to revolve therein, the said cylinderhaving an operating-crank, angular strips secured longitudinallytherein, adapted to receive the cream-holding tubes, and longitudinalopening, provided with a cover and perforations opposite the saidopening substantially and for the purpose set forth.

In testimony whereof We afiiX our signatures in presence of twoWitnesses.
